Most of the videos uploaded to YouTube are worthless. AI simplifies the creation, doesn't mean it's good and will be listened to. And if it will, then what's the problem? You can talk about ethics, IP, etc. but we're not even there yet.
Also, a lot of us value the fact that music is made by a person. Digital tools have been around for a long time and people have bickered about that, but ultimately they still require a person with some knowledge to sit down and actually produce the music, to do the thing. Writing prompts until you get something interesting can be fine, but what people are doing is carpet bombing us with whatever nonsense comes out because they have a financial incentive to do so.
I have plenty of experiments back when I did more digital music where I would mess with frequency modulators and such until I just found something interesting. I don’t see the harm in activities like that. But that’s not really what’s happening here. It’s deliberately lazy, corner cutting work to spam music platforms for profit. Yes there is a gray area between these two scenarios but that gray area isn’t the problem.
